Description: BSSAP, which stands for ‘Base Station Subsystem Application Part’, is a fundamental communication protocol in mobile networks, specifically within the context of the GSM (Global System for Mobile Communications) architecture. This protocol facilitates communication between the Mobile Switching Center (MSC) and the Base Station Controllers (BSC). BSSAP enables resource management and signaling necessary for establishing, maintaining, and terminating calls, as well as for data transmission. One of its most relevant features is its ability to handle user mobility, allowing mobile devices to move from one cell to another without losing connection. BSSAP is based on the SS7 signaling protocol, which provides high reliability and efficiency in information transmission. Additionally, it is responsible for managing user location information, which is crucial for billing and call routing. In summary, BSSAP is an essential component for the operation of mobile networks, ensuring that communications are seamless and efficient.
